Research Progress of Seismocardiography Signal Processing and Applications
Cardiovascular disease is one of the factors that seriously affect human life and health.How to use various detection methods for early health assessment and disease diagnosis of human cardiovascular system is an effective means to ensure people's life and health.Among them,the thoracic vibration signal(seismocardiography,SCG)caused by human heart beating can be used to describe fine-grained cardiac activity information,including the opening and closing of heart valves,which helps in the detection and diagnosis of cardiovascular diseases such as coronary heart disease,myocardial infarction,and cardiac bleeding.Moreover,thanks to the development of various lightweight sensors and non-contact sensors,long-term and daily monitoring of human SCG signals can be achieved.In recent years,researchers have become more specific in their study of SCG signals,and have made certain breakthroughs in the acquisition methods,signal denoising algorithms,feature extraction,and clinical applications of SCG signals.The research situation in the field of SCG signals in recent years from the above aspects is summarized and corresponding prospect is discussed.
